TIMING OR CONTROLLING MECHANISM.

Specification of Letters Patent.

Patented June 20, 1916.

Application filed March 14, 1913. Serial No. 754,211.

To all whom it may concern Be it known that I, RICHARD S. JACoBsEN, a. subject of the King of Norway, residing at Chicago, in the county of Cook and State oi Illinois, have invented certain new and useful Improvements in Timing or Controlling Mechanism, of which the following is a deJ scription.

My invention belongs to that general class of devices known as timing or controlling mechanism, and relates particularly to mechanism .applicable Jfor indicating time, or for controlling or operating suitable apparatus at predetermined intervals, which intervals may be varied as found desirable.

The invention has among its objects the production of a simple, compact, convenient,

accurate, efficient and satisfactory device of the kind described, `for use wherever 'found applicable.

To this end my invention consists in the novel construction, arrangement and combination of part-s herein shown and described, and more particularly pointed out in the claims.

In the (drawings, wherein like reference characters indicate like or corresponding pai'ts, Figure 1 is a sectional view of my device taken substantially on line 1, 1 of Fig. 2. Fig. 2 is a sectional view taken substantiallv on line 2, 2 of Fig. 1. Fig. 3 is a sectional view taken substantially on line 3, 8 of Fig. 1.

Referring to the drawings, 1 represents a suitable base upon which a shaft 2 is supported in any suitable manner, three brackets 3, 4 and 5 being shown for the purpose.

their equivalents, provided with movable cores 9 and 9, which are connected to the ends of the arms 7, 7 the same forming elec tromagnets of the type known as solenoidalmagnets. As the several parts upon opposite sides of the shaft 2 are substantially similar, I have given the similar parts the same reference characters with the eX- ception that the characters on o-ne part are primed in order to make the operation of the device more clear, as hereafter set forth. Any equivalent type of electro-inagnetic motor or the like may be employed.

Referring particularly to Figs. 2 and 3, the solenoid core 9 is connected to the arm 7 by links 10, which are pivotally secured to the arms and cores at points 11 and 12 rcspectively. The parts or arms 7 are so arranged that when one core is down in its v coil, the other core is raised, and therefore energizing the coil in which the core is raised -will draw the core down, the opposite core being drawn up. Raising or lowering the arms 7 rocks the collar G and the arms 6.

Suitable mechanism is provided arranged to cooperate with the arms 6, and control the energizing of the solenoid coils 8 and 8. At the end of each arm 6 is arranged a receptacle 15 provided with a suitable top 1G, the receptacle being supported or carried by a rod 17 pivotally secured at 18 to the arm G, the opposite receptacle being similarly constructed, as previously mentioned. The two receptacles are connected at their tops by a pipe or tube 22, which is preferably iiexible, or flexibly connected to the receptacles, so as to permit the same to be alternately raised and lowered when the arms 6 ai'e rocked about the shaft 2. lVithin each receptacle is arranged a float 23, of suitable material, which is preferably provided with a top plate 45 of suitable material, as hereafter described. The bottoms of the two receptacles are provided with pipes or tubes 24 and 24 respectively, which are connected by the pipes 25 and 25. As most clearly shown iii Figs. 2 and 3, aI valve casing 26 and valve 27 are provided between the two pipes, the two being preferably pivotally supported by a bracket 28 and screws 29. Enough fluid is placed iii the receptacle to raise the fluid in the lower one sufiiciently to bring the plate 45 into contact with suitable contacts on the covers or tops 16.

`As is obvious, when one receptacle, that is, the filled one, is raised, the fiuid passes through the bottom of the higher one through the pipes, 24 (see Fig. 2) 25, 25, and 24, to the other receptacle, where it raises the float in that receptacle until it makes Contact, electrically closing the circuit to energize the solenoid controlled by it, and reversing thc relative positions of the two receptacles, at which time the fluid Hows v 2 in any suitable manner.

the solenoid coil of the raised core. The time required for the flow of the fluid from one receptacle to the other may be varied or controlled by operating the valve 27, for instance the valve may be opened sufficiently to require one minute, or one-half minute, or any other interval, of time, for the fluid to flow from one to the other sufficiently to raise the floats and close the circuits.

The movement of the arms and tubular collar 6 may be transmitted to the shaft The connection is preferably so arranged that the shaft 2 is rotated periodically in one direction.

The construction shown to accomplish thisis a ratchet Wheel 31 (only a portion of the teeth being shown in Fig. 2), secured to the shaft 2, and arranged to coperate with a pawl 32 pivotally secured at 33 to one of the arms 6. As the arm 6 is rocked on the shaft it periodically rotates the shaft 2. In the drawings I have shown but one pawl secured to one of the arms, it being understood, however, that a suitable pawl, or equivalent, may be employed, so that the shaft is rotated during the rocking of the tubular part 6 and the arms in both directions. This rotation of the shaft 2 may be utilized wherever found desirable, the same being particularly convenient for clock mechanisms, since the device may be so arranged or controlled that the shaft may be rotated periodically, so that it makes one complete rotation per hour, the hand being regularly advanced at intervals of one or one-half minute, or any other desired interval. I have shown a minute hand 34 secured to the shaft 2, which is arranged to make one complete rotation every hour, and an hour hand 35 secured to a collar 36, suitably connected to the shaft and arranged to make two complete revolutions every twenty-four hours. The collar 36 may be connectedv to the shaft in any suitable manner. As shown, I provide the same with a gear 37, in mesh with the pinion 38 on the shaft 39, which is driven by a gear 40, meshing with the pinions 41 on the shaft 2. These gears are so arranged or proportioned that the hand 35 makes the only complete revolution for each twelve revolutions of the hand 34. The application of the device to a clock is particularly mentioned, since this is a particularly desirable and convenient use for the mechanism.

The top 16 of each of the receptacles is provided with a contact or binding post 51 and 52 suitably insulated from each other. A conductor 50 connects the binding posts 51 or contact with contact or binding post 49, grounding the same on the receptacle, shaft and frame, etc. The contact 52 is conneet-ed by a conductor 53 to a binding post 54. A battery B, or other source of energ is connected by a conductor 46 to a binding post 47 on the base 1, which is connected by a conductor 48 to the standard 3. The standard, shaft 2, arms 6 and rods 17, etc., electrically connect the receptacles to which the contacts 51 are grounded, and conductor 48. A conductor 59 from the battery is connected vto -a binding post 58.

It will be noted by referring to Fig. 1, that one receptacle is connected to the binding post 54 and the other to the binding post 54. The binding post 54 is connected by a conductor 55 to the solenoid coil 8, and the solenoid coil 8 by a conductor 56 and conductor 57 to the binding post 58. The binding post 54 is connected by a conductor 55 to the solenoid 8, and the solenoid coil by a conductor 56, and a conductor 57, to the binding post 58.

Assuming that the parts are as shown in the drawings, with the receptacle 15 raised and the receptacle 15 in its lower position: As soon as suiiicient iuid has passed into the receptacle 15', to raise the float 23, so that the plate contacts with the contact members 51 and 52', closing the circuit, a circuit is then formed as follows: battery B, 46, 47, 48, and through the bracket 3, shaft 2, and arm 6, etc., to the post 49, conductor 50 to contact 51, through plate 45 to contact 52, conductor 53, binding post 54, conductor 55, solenoid 3, conductor 56, 57, binding post 58, conductor 59, to the battery. Coil S is therefore enel'- gized, drawing the coil core 9 down, and with it the receptacle 15, thereby elevating the receptacle 15', so that the fluid flows back to receptacle 15, when the other circuit is closed in a similar manner. As the core 9 vis pulled down each time, the pawl 32 partically rotates the ratchet wheel 31, thereby partially rotating the shaft 2, and as the core 9 is pulled down, the pawl takes a new purchase on the ratchet wheel, so as to partially rotate the shaft at the next operation. As previously mentioned, the parts may bc so arranged that the hand 34` makes twentyfour rotations in t\.'e1it v-four hours, and the hand 35 makes two complete rotations in twenty-four hours.

Having thus described my invention. it is obvious that various immaterial modifica-- tions may be made in the same without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement or combination of parts herein shown and described, or uses mentioned.
